CARRIER FOR CABLE-CARRIER APPARATUS.

To all whom it may concern Be it known that I, GEORGE A. AMSDEN, of Littleton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Carriers for CableCarrier Apparatus, of which the following is a specification.

My invention relates to improvements in carriers for cable carrier apparatus, and its object is to provide a spring clamp for the carrier by which the same may be engaged with or disengaged from the actuating or driving cable for transmitting or delivering the carrier.

In the accompanying drawings which illustrate a construction embodying my invention, Figure 1 is a front elevation of a cable cash carrier showing same in engagement with the driving cable. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view and Fig. 4 is a sectional View on the line 4l-t Fig. 1 looking in the direction indicated by the arrow. Fig. 5 is a detail perspective view showing the fixed jaw of the clamping mechanism.

Like letters of reference refer to like parts throughout the several views.

A represents a cable cash carrier for transmitting cash, sales slips etc. and has a cover B hinged to the carrier and held normally open by spring D. Pivoted to the cover B at G is a lock lever F which is adapted to be manually operated to be moved into or out of engagement with the lip E on the carrier A to lock closed or permit the opening of said cover.

H is an angle plate extending through a slot in the top of the carrier and secured to the inside of said carrier by suitable rivets J.

K is the stationary jaw of the cable clamp and is riveted to the upper part of the plate H and carries the ears X projecting through apertures in said plate and in which ears is mounted the pin or pivot M.

N is a movable jaw of the cable clamp and is hinged at its lower end on the pivot M.

L is a spring mounted on the pivot M and is supported at the ends by the jaws K and N and is adapted to pinch the jaws closely together whereby the same may grip the cable.

P is a stop on the upper end of the plate H and projects through and is adapted to limit the outward movement of the jaw N.

Specification of Letters Patent.

Application filed April 6, 1908.

Serial No. 425,316.

The outer ends of the jaws N and K are flared outwardly and between'their inner ends is an enlarged circular opening or recess. On the inner faces of the opposing aws and extending lengthwise of the same at right angles to their pivotal connection are the ribs S with their ridges forming sharp biting edges, as shown in Figs. 8 and 5. 'i and V are two fiber pieces secured together by screws U passing through the plate H, and they cover the spring L and the pivot M to protect the same.

In operation the carrier is placed in the ways of the cable System and the clamp is forced onto the cable R, the movable jaw N opening against the action of the spring L to admit the cable to the enlarged circular opening between the inner ends of the jaws. When the cable is engaged by the clamp the sharp opposing edges of the ribs S on the inner faces of the jaws bite into the cable, being forced thereto by the spring L. As the biting edges extend transversely across the cable the latter is firmly held against slipping longitudinally through the clamp. Owing to the fact that the ribs extend lengthwise of the jaws at right angles to their pivotal connection the clamp can be easily forced onto and off the cable, as the ribs moving in the direction of their length across the cable offer but little resistance. Also, owing to the enlarged circular opening between the inner ends of the jaws there is little or no tendency of the clamp to leave the cable while th carrier is in transit. It is to be observed that the spring L continuously presses the aws N and K together and that the clamp is slipped onto and off the cable simply by forcing the jaws onto and off the same, no manipulation of the spring by special mechanism being required.

Having thus described the nature of my invention and set forth a construction e1nbodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. Cable carrier apparatus comprising in combination a cable and a carrier, said carrier provided with yielding means for detachably attaching it to said cable, said means comprising a clamp having two opposing jaws, one at least of which is flared to permit of the ready insertion of said cable between said jaws and one at least of said jaws further being provided with means for partly encircling said cable when soinserted and resilient means for continuously pressingone of said jaws toward the other while the clamp is being forced onto or oil of said cable and while it is in carrier transmitting engagement therewith, one at least of said jaws being provided with a rib positioned to bite into the cable.

2. In a carrier for cable carrier apparatus,

a clamp comprising opposing jaws to receive the propelling cable, spring mechanism continuously pressing the jaws together, and opposing ribs extending longitudinally along the inner faces of the jaws so as to move in the direction of their length transversely across the cable when the clamp is forced onto or off the cable.

3. In a carrier for cable carrier apparatus, a clamp comprising opposing jaws flared at their outer ends and having an enlarged opening between their inner ends to receive the cable after the latter has been forced between the flared outer ends of the jaws into the recess, spring mechanism continuously pressing the jaws together, and opposing ribs with sharp edges extending longitudinally along the inner faces of the jaws so as to move in the direction of their length transversely across the cable when the clamp is forced onto or off the cable.

L. In a carrier for cablecarrier apparatus, a plate attached to the carrier, a fixed jaw on one side of said plate, ears on said fixed jaw projecting through said plate, a jaw on the opposite side of said plate, a pin pivoting said second jaw between said ears, a stop on said plate limiting the outward move ment of said pivoted jaw, opposing ribs on the inner faces of said jaws extending longitudinally of the same and transversely of the path of travel of the cable between the jaws when the carrier is in position to be propelled,- and a spring normally pressing said aws together so that said opposing ribs will grip the cable. I

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this twentyseventh day of March A. D. 1908.

GEORGE A. AMSDEN.
